[0004] 1. During the unwinding process, the braid needs to be in a tensioned state so that it is easy for the human eye to inspect it intuitively;

[0005] Second, based on the inspection based on human eyes, the unwinding speed needs to be controlled to prevent the tape from being transmitted too fast and causing the human eye to fail to inspect accurately. Summary of the invention

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, a semi-automatic carrier tape unwinding device 10 for assisting manual inspection of braided tape comprises: a support frame 100, a driving shaft 200, a driven shaft 300, a unwinding material tray 400, and a winding material tray 500.

[0040] like Figure 3 As shown, the driving shaft 200 and the driven shaft 300 are rotatably disposed on the support frame 100 , respectively, and the driving shaft 200 and the driven shaft 300 are connected to each other through a conveyor belt 600 .

[0041] like Figure 3 As shown, the conveyor belt 600 is wound in an "8" shape so that the driving rotating shaft 200 and the driven rotating shaft 300 rotate in opposite directions to each other.

[0042] like Figure 3 As shown, a reverse speed limiter 700 is fixedly disposed on the driven rotating shaft 300 , and the unwinding material tray 400 is rotatably disposed on the driven rotating shaft 300 via the reverse speed limiter 700 .

[0043] like Figure 3 As shown, the winding material tray 500 is rotatably disposed on the driving shaft 200 .

[0044] like Figure 3 As shown, the unwinding material reel 400 is used to unwind the braid 20 , and the rewinding material reel 500 is used to rewind the braid 20 .

[0045] like Figure 4 and Figure 5 As shown, specifically, the reverse speed limiter 700 includes: a sleeve 710 and a ball 720 .

[0046] like Figure 5 As shown, the sleeve 710 is fixedly sleeved on the driven shaft 300 , and a receiving groove 711 is formed on the outer surface of the sleeve 710 , and the ball 720 is movably disposed in the receiving groove 711 through an elastic member 730 .

[0047] The unwinding material tray 400 has a through hole 410 at its center (eg Figure 3 As shown), the unwinding material tray 400 is rotatably sleeved on the outer surface of the sleeve 710 through the through hole 410.

[0048] The sleeve 710 rotates along with the driven shaft 300 , so that the ball 720 undergoes centrifugal motion, thereby causing the ball 720 to abut against the hole wall of the through hole 410 and generate friction. The rotation direction of the sleeve 710 is opposite to that of the unwinding tray 400 .

[0049] Furthermore, the active rotating shaft 200 is provided with a driving handle 210 (such as Figure 3 shown).

[0050] Next, the working principle of the semi-automatic carrier tape unwinding device 10 for assisting manual inspection of the braided tape is described:

[0051] The unwinding material tray 400 is loaded with the braid 20 to be unwound, and one end of the braid 20 is connected to the winding material tray 500;

[0052] The driving shaft 200 is rotated by shaking the driving handle 210, and the driving shaft 200 drives the driven shaft 300 to rotate in the opposite direction through the conveyor belt 600 wound in an "8" shape; it should be particularly noted that the driving shaft 200 and the driven shaft 300 always rotate in opposite directions, for example, when the driving shaft 200 rotates clockwise, the driven shaft 300 rotates counterclockwise, and when the driving shaft 200 rotates counterclockwise, the driven shaft 300 rotates clockwise;

[0053] like Figure 6 As shown, in a normal inspection state, when the active rotating shaft 200 rotates clockwise, the driven rotating shaft 300 rotates counterclockwise, the active rotating shaft 200 drives the winding material tray 500 thereon to rotate clockwise, the clockwise rotating winding material tray 500 drives the unwinding material tray 400 thereon to rotate clockwise, and the driven rotating shaft 300 drives the reverse speed limiter 700 thereon to rotate counterclockwise;

[0054] During the counterclockwise rotation of the reversing speed limiter 700, under the action of centrifugal force, the balls 720 in the receiving groove 711 on the sleeve 710 will spread outward, and the balls 720 will contact the hole wall of the through hole 410 in the unwinding material tray 400 and generate friction force;

[0055] Due to the existence of the friction force and the counterclockwise rotation of the reversing speed limiter 700, the unwinding material tray 400 will be subject to the resistance of the ball 720 when rotating clockwise, so the braid 20 between the unwinding material tray 400 and the winding material tray 500 will be in a taut state, and the braid 20 can be unwound normally and properly taut, which facilitates the inspection personnel to inspect intuitively;

[0056] When the driving handle 210 is shaken to make the active rotating shaft 200 rotate faster, the above-mentioned friction force will be significantly increased. This increased friction force will seriously hinder the normal rotation of the unwinding material tray 400, making it difficult for the unwinding material tray 400 to rotate. The inspector feels obvious resistance, which reminds the inspector not to rotate too fast. Too fast rotation speed will affect the quality of inspection. The inspector can only shake the driving handle 210 at an appropriate speed, which is equivalent to installing a speed control sensor on the unwinding device to remind the inspector.

[0057] During the inspection process, if a quality problem is found, the driving handle 210 is shaken in the opposite direction, the active shaft 200 rotates in the opposite direction, and the winding material tray 500 also rotates in the opposite direction, so that the originally tightened braid 20 will be in a relaxed state, and the inspector will cut out the problematic part and reconnect the broken part with tape;

[0058] Continue to shake the driving handle 210 in the forward direction to resume the inspection state.

[0059] like Figure 3 As shown, in the present invention, a winding reel limiter 800 is provided on the driving rotating shaft 200 , and an unwinding reel limiter 900 is provided on the driven rotating shaft 300 .

[0060] The structure of the winding reel stopper 800 is the same as the structure of the unwinding reel stopper 900 .

[0061] like Figure 7 As shown, the winding reel limiter 800 includes: a winding reel holding block 810 , a winding reel pressing spring 820 , a winding reel fixing sleeve 830 , and a winding reel fastener 840 .

[0062] like Figure 7As shown, the winding reel holding block 810 is slidably sleeved on the active rotating shaft 200, and the winding reel fixing sleeve 830 is fixedly sleeved on the active rotating shaft 200 through the winding reel fastener 840. A winding reel clamping spring 820 is provided between the winding reel holding block 810 and the winding reel fastener 840. The winding reel clamping spring 820 is used to provide elastic force for the winding reel holding block 810 so that the winding reel holding block 810 is pressed on the winding material reel 500.

[0063] Similarly, the unwinding reel limiter includes: an unwinding reel holding block, an unwinding reel clamping spring, an unwinding reel fixing sleeve, and an unwinding reel fastener; the unwinding reel holding block is slidably sleeved on the driven rotating shaft, the unwinding reel fixing sleeve is fixedly sleeved on the driven rotating shaft through the unwinding reel fastener, and an unwinding reel clamping spring is provided between the unwinding reel holding block and the unwinding reel fastener, and the unwinding reel clamping spring is used to provide elastic force for the unwinding reel holding block so that the unwinding reel holding block is pressed on the unwinding material reel.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
